<div>hey techs</div>
<div> </div>
<div>i've got a rebuilt (rebuilt 2 or 3 years ago) 1890's Knabe upright. nice warm, woody sound, and it's already been used in a few recordings. i'd like to have it sound nice for many more years. i do have one concern. i've noticed a crack or two in the soundboard, and it bums me out to have a rebuilt, beautifully sounding piano with a crack in the soundboard. </div>
<div>now i did a few shims at nbss on grands we were rebuilding, but never any uprights... and in the following post <a href="https://www.moypiano.com/ptg/pianotech.php/2006-January/184497.html">https://www.moypiano.com/ptg/pianotech.php/2006-January/184497.html</a>, David Ilvedson says you can't shim from behind. </div>
<div>so my question is can <em>anything</em> be done to fix the cracks?</div>
<div> </div>
<div>as always, any help is greatly appreciated.</div>

<div>thanks</div>
